My first reaction upon seeing your question was to say "um, no, that can't be done", but a reader, Marie C., pointed out that it was indeed quite possible to accomplish with a little bit of finagling.

Thanks, Marie, it's helpful to have people watching my back! :-)

The key is to pay attention to the "power search" link that's part of the result of a search on the iTunes Store.

Here's what I mean:

I'll start with a simple search for a favorite artist of mine, the talented Kate Bush. I do this by simply typing her name into the iTunes Store search box on the top right corner of the Apple iTunes application:

The result offers a bunch of different things, including a "Power Search" link, a list of matching artists, popular albums, and so on:

For any of these links, it turns out that I can easily copy the URL. For example, the Power Search URL, as Marie suggested:

More interestingly, though, is to select the matching Artist entry:

Does it work? Here's the URL I got from copying the artist match for "Kate Bush":

http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewArtist?id=487277

Click on it, see what happens in your browser.

Neat, eh? Now you're good to go with a couple of alternatives for your MySpace profile page.
